To-aZZ wwmfz't may concern Be it known that I, PAUL T.VF1EIHiti-iiz, a

citizen of the United States, residing at Maplewood, inthe county Vot St. Louis and State of'Missonri, have invented certain new and useful Improvements in Nut Locks, of'

which the following is .a specification.

\ My presentinventionrelatesto nut-locks,-

and the object of my invention is to .provide a lock` more particularly adapted to rail joints; whichv will 'securelylock the nuits; on

alternate bolts upon both-sides vot the connected rails and hold the nuts `against accidental rotation, or removal, thus positively holding thefish .plates uponopposite sides of 'the connected rails inr thepnoper posa tion. l

further obj-ect ofttheuinvention is to provide sifmplezianfd inexpensivei nut-lock` ingldevice :capableof `being efect'ively appli-ed to 'i'.ailfjgoints, .especially Vwhere fevery.

other bolt isreversed so` that the mit :one boltrvisupon one side of the rail-:and the niit of ythe "next holt will-heupen 'the loppositie side of the rail, which is thelatestmet'hod ot arranging bolts and nuts, vsed in :rail join-t connections.

15 I e A furtlrerzobjectpt the intention as :the provision et .a nut .locking device capable of locking the nut Aupon the first and third bolt in a row by means ot separate locltplates and connecting the lock-plates through the medium of a third, or bearing plate, which is held in position by means of the second, or intermediate bolt in the row.v4

A'still further object of the invention is the 'provision' of means for connecting the lock-plates with thebearing plate'to-pre'- vent accidental rdisconnection of the lockplatestherewith'. I

With the above and other objects in view, the invention consists in the .novel features of construction, arrangement andrombination of parts hereinafter more fully described and iinally pointed out inthe claims 'y hereto appended.

Referring to the accompanying drawings forming a part of this specification wherein like characters yof reference denote similar` acififatia .f mais Item- Patented Aior., 25,1922( Application' filed February y17g-"1921;v 'serial no. 445,791. y Y` characters 1 and 2 indicate the :meetingend's of two fadjiaeentrra-ilsheld" against Elateral `r displacement by means et. the 'fish-plates 3.

.carrying out theiaim of presenti invention, which lis .an improvement over myU; S..-Iuetters Patent, NnmberfLO 1,635, I'zemplfoy abearing plate. 6 -havinga central opening/7 for fthepassageoiione of the bolts 4 :nearestfstherail jointf.' v :This central opening .is elongated so -as :to-,neceive the flattened shoulder 9 ofthe bolts 4 to prevent the bearing plate 6 from rotary displacement from any cause. The bolt 4 carryingthe plate 6 is'intermediate two adjacent bolts, and the head of the bolt engages the plate 6, as shown in Figs.1 and 2.0i the drawings, for holding the plate in contact with the fish-- plate. The ends of the bearing plateG are so l' bifurcatedV so that thecentral lipportionl may be rolled back to lform a lateral pro-A jecting vertically disposed looped key holder v `10 at leach end-fot the bearingplateyas clearly shown iny Fig. 5.

Each nut 4 issecurely held against laccidental rotation, or removal throughthe'ine-v dium of a'lock-plate 11 having a ynutlreceiv.- ing opening 12 and a key holder receiving opening The lock-platell has its longi- Vtudinal edges ybent rearwardly at :a right angle to form 'a channel plate of the-lock- -1 plate to permit the lock-plate to straddle the bearing plate, as shownin Fig. 3. As shown in Figs. 1 and 2, there is a lockplate 11 for each bolt and nut 4 and 5, respectively. It v'will be observed that the. nut

4 is receivable in the opening` 12 and thatthe key holder is receivable in the opening 13 thereof. A suitable pin, or cotter key 14 is vemployed to pass through each key holder 10 and engage the outer face oi the lock-plate 11 to prevent accidental removal of the lockplate. It will be clearly seen from Figs. l and 2 of the drawings, that when the lockplate is applied and the key 14 applied, that the nut 4 is securely held against any possi# ble accidental displacement, rotation, or removal and that the lock-plate is held from displacement by means of the pin, or key 14.

For a rail joint, there are two sets of nutlock devices employed, one upon each side of the rails, as shown in Fig. 2, thus it will be seen that each nut-lock device locks the nut of one boltV of each rail 1 and 2, as shown in Fi 2.

From the ioregoing description, it is evident that I have provided a nut-lock device, especially designed for rail-joints, although not necessarily limited thereto,y and that the deviceis simple in construction, durable and v that it can be readily and easily applied to Vstructionshovvn and described, but desire to have it understood that the invention I have vshown in the drawings is merely illustrative, as it is manifest that various minor changes may be'made in the form, shape and particular.arrangements of parts without departing from the spirit of my invention, hence I reserve the right to make any such changes, or modifications as mayV fairly fall within the scope of the appended claims when fairly construed.

What I claim is:

1. A nut locking device comprising a central apertured bearing plate held in position by the head of a bolt upon either side of a rail joint, a laterally extending loop formed-at each end of saidl bearing plate, 'a pair of opposed lock plates each having an opening for the reception of the nut of a bolt on either side of the bolt holding the bearing plate and each lock plate also being provided with an opening tor the reception of the looped ends of the bearing plate, and a pin carried by each loop to retain each plate in a locked position with the bearing plate and prevent accidental rotation of the nuts of the outer bolts during vibration of the parts connected by the bolts.

2. A nut locking device comprising a central apertured bearing plate held in position by the head of a bolt upon either side'of a rail joint, a vertically disposed loop formed at one end of the bearing plate and extending laterally from the plate, the lock plate having an opening to receive the nut of an adjacent bolt and said'plate having an open-
